Version bump to 5.9 should fix this, I think
A fix is urgently needed: The new version of media-libs/tiff (new slot) forces a rebuild of rawtherapee, and the rebuild fails. Hence, both emerge @world and emerge @preserved-rebuild fail, and masking raw-therapee does not help.
As far as I can tell, the problem is the following: The preprocessor expands the wchar.h:582 line containing the error to extern __FILE *open_wmemstream (wchar_t **__bufloc, size_t *__sizeloc) noexcept (true) __attribute__ ((__malloc__)) __attribute__ ((__malloc__ (fclose, 1))); And when the compiler reads that line and processes the __attribute__, it really has *two* different, incompatible definitions of "fclose" in scope, which makes argument 1 of __malloc__ ambiguous: * The stdio.h "extern int fclose (FILE *__stream);" * And "void fclose (IMFILE* f);" from rawtherapee-5.8/rtengine/myfile.h:58 If the fclose in myfile.h is renamed to something else (e.g. xxxfclose), the open_wmemstream line above compiles without error. (but the generated code is most likely broken, because it calls the wrong fclose?). So I think the problem is not in rawtherapee, and not in gcc, but in glibc: If glibc's headers are included in C++ where function overloading is allowed, and fclose is overloaded, __attr_dealloc_fclose results in the ambiguous error (as would __attr_dealloc_free if the application declared its own free).
I found a workaround which seems to solve the problem for me: In rawtherapee-5.8/rtengine/myfile.cc, just move #include "myfile.h" down two lines (after #include "rtengine.h") to make sure that all the standard headers are included *before* rawtherapee's declaration of its own fclose. emerges for me and produces an executable which starts (I did not test if it also works correctly).
(In reply to Ben Kohler from comment #9) > Version bump to 5.9 should fix this, I think I believe so as well. This bug should be fixed upstream in this commit: https://github.com/Beep6581/RawTherapee/commit/2e0137d54243eb729d4a5f939c4320ec8f8f415d 5.9 has this, but the code from 5.8 differs too much to backport the fix as-is. Would it be possible to package 5.9?
